Relax.
Pay attention to details, ask questions of photographer like lighting (whether it's going to hard or diffused, flash or no flash, using filters, shooting B&W). All the info you get from the photog will help you decide how to apply the m/u. Hard lighting in general washes out m/u, so you have to apply twice as much. Makeup for shoots generally looks 2ce as much than other types of makeup. But apply it in thin layers, so it doesn't just look like you packed it on.
Set a time limit for yourself for turning out the talent prepared (an hour, hair mu).
Start with clean beauty mu. Save the creative stuff for much later.
Pack what you think you need. Don't pack everything. Get as much info on the concept of the shoot, so you can take what you need plus a little extra. You don't want to pack everything and have people at the shoot who "borrow" stuff. Try and palette everything in simple palettes, so no one knows that's Dior lipstick and want it. be watchful with your kit.
Think about why you are doing something before you do it e.g: why am I shadowing her crease? does the talent need shadow in her crease or will it help her eyes more if I shadow above the crease, on the fold? (usual treatment for those with heavy creases). Think while applying. Instinct comes with practise.
Try and avoid over-shimmery products, mineral face powders and spf in a lot of your products. It can look greasy.
Work a little longer on the skin. If your e/s is flawless and the talent's skin is splotchy, it's not going to be good. Do such a good job on the skin, it'll need little retouching. Also pay attention to brows. Blend well, because the camera picks up everything.
Find out beforehand from the photog how long it will be before you get images back. You don't wanna shoot and get nothing from it.
HTH, have fun!
